Writing without Reason?

I generally have two or three books I'm working on reading at any given time. Currently my non-fiction book of choice is Stephen Hick's "Explaining Postmodernism". So far it's been an excellent read for anyone wanting to understand some of the broad philosophical trends of the last few centuries. Currently I'm working through chapter 4 - "The Climate of Collectivism". I'm marveling over the impact that someone like Rousseau seems to have had over philosophy in recent history.

Whatever else he may have said aside, anyone who writes theses about reason being the root of mankind's unhappiness, and that we must abandon it in order to be happy, really ought to look to his own house first. As someone who has written volumes over the years, I think I can honestly say that one cannot write a sentence without applying reason, much less an entire treatise on any given subject.

I'll give him one thing, mankind would have been much happier if he had followed his own advice.
